Unless otherwise specified, the embodiments in this application can be combined with each other.

[0018] Please see Figure 1 , Figure 2 and Figure 3A film cutting machine includes: an equipment frame 1, a fixed plate 2, a movable frame 3, a movable plate 4, and a hydraulic cylinder 5.

[0019] The equipment rack 1 has a set of rail channels 1a, more specifically, there are two rail channels 1a, symmetrically arranged on the left and right sides of the equipment rack 1. The rail channels 1a include: a vertical section and a horizontal section connected to the lower side of the vertical section.

[0020] The fixing plate 2 is fixedly connected to the equipment frame 1. The fixing plate 2 has a vertical first plane 2a, on which multiple cutting blades 2b and multiple creasing blades 2c are mounted. The multiple cutting blades 2b form a closed shape, that is, the cutting blades 2b cut the required shape on the paper. The creasing blades 2c press creases at the positions where the paper needs to be folded, facilitating subsequent folding of the paper.

[0021] In some embodiments, the fixing plate 2 is detachably connected to the first mounting plate 7. Multiple cutting tools 2b and multiple indentation tools 2c are all mounted on the first mounting plate 7.

[0022] Multiple first mounting plates 7 can be set up, and the multiple cutting blades 2b and multiple creasing blades 2c of each first mounting plate 7 correspond to a type of paper with a different shape and size. When the shape and size of the paper change, the first mounting plate 7 is removed and the corresponding first mounting plate 7 is installed.

[0023] Please see Figure 2 In some embodiments, two concave strips 8 are fixedly connected to the first plane 2a of the fixing plate 2. These two concave strips 8 are positioned one above the other, and the first mounting plate 7 is detachably connected to the recesses of the two concave strips 8. Accordingly, the widths of the multiple first mounting plates 7 must be identical.

[0024] More specifically, the upper and lower outer walls of the first mounting plate 7 can each have multiple threaded holes, and the two concave strips 8 can each have multiple through holes. The first mounting plate 7 is slidably inserted into the recesses of the two concave strips 8, with its upper outer wall fitting against the inner top wall of the upper concave strip 8 and its lower outer wall fitting against the inner bottom wall of the lower concave strip 8. The position of the first mounting plate 7 is adjusted so that the threaded holes and through holes correspond one-to-one, and screws are used to fix the first mounting plate 7 to the two concave strips 8.

[0025] Please see Figure 7 and Figure 8In some embodiments, the upper concave strip 8 can be adjusted in a vertical direction to fix its connection position. Accordingly, on the one hand, the widths of the multiple first mounting plates 7 can be different. On the other hand, the installation / removal of the first mounting plate 7 can be accomplished by adjusting the upper concave strip 8. Taking the installation of the first mounting plate 7 as an example, firstly, the upper concave strip 8 is moved upward to increase the distance between the two concave strips 8, then the first mounting plate 7 is inserted downward into the recess of the lower concave strip 8, and finally, the upper concave strip 8 is moved downward so that the first mounting plate 7 is inserted into the recess of the upper concave strip 8.

[0026] More specifically, the equipment frame 1 may have two convex grooves 1b, with a square nut inside the wider groove of the convex groove 1b; the upper concave strip 8 may have perforated extension pieces 8a on both the left and right sides, with bolts passing through the extension pieces 8a and threaded to the square nuts. Tightening the bolts fixes the upper concave strip 8, while loosening the bolts allows the upper concave strip 8 to move up and down.

[0027] Please see Figure 1 The movable frame 3 is fixed with a first connecting end 3a and a second connecting end 3b. More specifically, there are two first connecting ends 3a, which are symmetrically arranged on the left and right sides of the movable frame 3. There are also two second connecting ends 3b, which are also symmetrically arranged on the left and right sides of the movable frame 3.

[0028] The first connecting end 3a is hinged to a first slider 3a1, which is horizontally slidably connected to the equipment frame 1. More specifically, a first linear guide 9 can be used, which is fixedly connected to the equipment frame 1, and the first slider 3a1 is fixedly connected to the first mounting slider that matches the first linear guide 9.

[0029] A pin pair is provided between the second connecting end 3b and the groove rail 1a. More specifically, a needle roller bearing can be installed on the second connecting end 3b as a pin, and the pin is matched with the groove rail 1a, that is, the outer ring diameter of the needle roller bearing is equal to the width of the groove rail 1a.

[0030] Correspondingly, when the first connecting end 3a moves in the groove 1a, the first slider 3a1 will move relative to the equipment frame 1, and the first connecting end 3a will also swing relative to the first slider 3a1.

[0031] The movable plate 4 is fixedly connected to the movable frame 3. Correspondingly, when the first connecting end 3a moves in the groove rail 1a, the movement of the movable plate 4 is composed of a combination of horizontal sliding and swinging.

[0032] Please see Figure 3The movable plate 4 has a second plane 4a, within which a set of support blocks 4b, a set of limiting blocks 4c, and multiple pressure grooves 4d are installed. Accordingly, paper is placed on the movable plate 4. There can be multiple support blocks 4b, used to support the lower edge of the paper; there can be two limiting blocks 4c, used to abut the left and right edges of the paper respectively.

[0033] In conjunction with the above embodiment where "the fixed plate 2 is detachably connected to the first mounting plate 7", in some embodiments, a set of support blocks 4b are fixedly connected to the movable plate 4, and a set of limiting blocks 4c and multiple pressing grooves 4d are magnetically connected to the movable plate 4. More specifically, for the pressing groove 4d, two magnetic strips can be used, with a gap between the two magnetic strips to form the pressing groove 4d.

[0034] Please see Figure 7 and Figure 9 In some embodiments, both a set of support blocks 4b and a set of limiting blocks 4c have gaps for the paperboard to enter. Accordingly, when the paper is placed on the movable plate 4, the left and right edges of the paper are first inserted into the gaps of the limiting blocks 4c, and then the paper is moved so that the lower edge of the paper is inserted into the gaps of the support blocks 4b, making the paper more stable during the movement of the movable plate 4.

[0035] Please see Figure 4 The hydraulic cylinder 5 is hinged to the equipment frame 1. The piston rod of the hydraulic cylinder 5 is hinged to the movable frame 3. More specifically, a connecting rod is fixedly connected between the two second connecting ends 3b, and the piston rod is hinged to the connecting rod. Accordingly, as an actuator, the hydraulic cylinder 5 needs to be used with a corresponding hydraulic system, solenoid valve, etc., so that the piston rod of the hydraulic cylinder 5 can extend and retract, and can be held in the extended or retracted position.

[0036] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 The hydraulic cylinder 5 is positioned at the hinge point on the equipment frame 1. During the extension of the piston rod of the hydraulic cylinder 5: the second connecting end 3b starts from the second end of the horizontal section away from the vertical section, moves horizontally first from the second end to the first end of the horizontal section, and then enters the vertical section and moves upward along the vertical section. Conversely, during the retraction of the piston rod of the hydraulic cylinder 5: the second connecting end 3b starts from the upper end of the vertical section, moves downward along the vertical section, and then enters the horizontal section and moves horizontally from the first end to the second end of the horizontal section.

[0037] Please see Figure 5 When the second connecting end 3b corresponds to the first end of the horizontal section near the vertical section, the second plane 4a is vertical, and the multiple pressure grooves 4d correspond one-to-one with the multiple indentation tools 2c.

[0038] Initially, the piston rod of the hydraulic cylinder 5 is in the extended position, and the movable plate 4 is tilted with a small tilt angle, which is close to horizontal, making it relatively convenient to place the paper on the movable plate 4.

[0039] After the paper is placed, the piston rod of the hydraulic cylinder 5 retracts. During this process: First, the second connecting end 3b moves downward along the vertical section. Correspondingly, the movable plate 4 swings, increasing the tilt angle. At the same time, the movable plate 4 also moves horizontally away from the fixed plate 2. Next, the second connecting end 3b enters the horizontal section near the first end of the vertical section. The movable plate 4 swings to the vertical position. Correspondingly, the second plane 4a also becomes vertical, and the multiple pressure grooves 4d correspond one-to-one with the multiple creasing cutters 2c. Finally, the second connecting end 3b moves horizontally from the first end to the second end of the horizontal section. Correspondingly, the movable plate 4 remains vertical and moves horizontally towards the fixed plate 2. The multiple cutting cutters 2b contact the paper and cut it. The multiple creasing cutters 2c cooperate with the multiple pressure grooves 4d to press out creases at the corresponding positions on the paper.

[0040] After the paper is cut and creasing is completed, the piston rod of the hydraulic cylinder 5 extends, and the movable plate 4 returns to its initial state, making it easier to remove the paper.

[0041] Please see Figure 7 and Figure 8 In some embodiments, the membrane cutting machine further includes a set of third connecting sections 6. More specifically, this set of third connecting sections 6 can be two. The first end of the third connecting section 6 is hinged to the movable frame 3. The second end of the third connecting section 6 is hinged to a second slider 6a, which is slidably connected to the equipment frame 1. More specifically, a second linear guide 10 can be used, which is fixedly connected to the equipment frame 1, and the second slider 6a is fixedly connected to a second mounting slider matched with the second linear guide 10.

[0042] The addition of a third connecting section 6 makes the movable frame more stable. Correspondingly, if combined with the above embodiment where "the fixed plate 2 is detachably connected to the first mounting plate 7", the third connecting section 6 may block the first mounting plate 7 from being inserted into the recesses of the two concave strips 8. This can be addressed by combining with the above embodiment where "the upper concave strip 8 can be adjusted in the vertical direction to fix the connection position".
